SpaceX Starship V3 Completes Flight 12 With Block 3 Architecture

BOCA CHICA, Texas — SpaceX achieved a significant engineering milestone this week when Starship completed Flight 12, the first test of the new Block 3 architecture that will ultimately carry astronauts to the Moon and Mars.

Block 3: A New Generation

The Block 3 Starship represents a comprehensive redesign. Engineers worked through hundreds of changes focused on the Raptor engine cluster, heat shield performance, and propellant management. The new Raptor engines deliver improved thrust and reliability, while the upper stage received a revised tile arrangement designed to better survive re-entry heating.

Flight 12 by the Numbers

The flight reached approximately 235 kilometers altitude before controlled descent. The Super Heavy booster executed a successful return and was caught by the "Mechazilla" tower arms for the third time in program history. Total mission duration was approximately 65 minutes.

What Changed From V2

The Block 3 Starship features a taller propellant tank section adding ~10% more capacity, and a redesigned nosecone to improve aerodynamic performance and accommodate the Artemis lunar lander payload bay configuration.

The Road Ahead

With Flight 12 logged as a success, SpaceX is preparing Block 3 Ship No. 2 for its own test flight in eight to twelve weeks pending FAA licensing. A crewed Artemis mission using Starship as a lunar lander remains on NASA's schedule, and each successful test brings that goal closer.
